Title: Negative voltage generator for semiconductor memory device
Inventor: SIM JAE-YOON
IPC: H02M3/07
Filed: 2002-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a negative voltage generator for a semiconductor memory device. SOLUTION: The negative voltage generator is controlled responsive to a word line precharge signal. Voltage fluctuations in a negatively biased work line schema is reduced by using a kicker circuit to provide a predetermined amount of negative charges to shut off a work line during a precharge operation. The negative voltage generator comprises first and second negative charge pumps. The second charge pump is activated responsive to the work line precharge signal. A negative voltage regulator can be used to regulate a negative voltage signal. A level shifter uses two voltage dividers and a differential amplifier to reduce response time, ripple of an output signal, sensitivity to process and temperature. The negative voltage regular cancels ripple from the charge pump to provide a stable negative bias voltage and reduce the amount of charge needed to precharge the word line.
